Patrick Alfred Kingsley MOCKFORD, Pilot Officer (Navigator), 207 Squadron, Royal Air Force Volunteer Reserve. Killed when his aircraft was shot down in Denmark. Aged 20

It was 20 year-old Patrick's 19th mission. Also on board were Warrant Officer (Pilot) 930246 Kenneth Royston Rees (aged 21); Sergeant (Flight Engineer) A/14063 George Tyler, Royal Canadian Air Force (aged 22); Sergeant (Air Bomber) 1383884 Thomas Edward Ellingham (aged 29); Flying Officer (Wireless Operator/Air Gunner) 136345 Leonard Foulds (aged 23);  Sergeant (Air Gunner) 1578147 Stanley William Cowham (aged 20), and Sergeant (Air Gunner) 1370576 Alexander William Cochrane (aged 20).

Some 207 aircraft - 68 Lancasters, 60 Halifaxes, 47 Wellingtons, and 32 Stirlings participated in the minelaying operation. 167 aircraft laid 593 mines off Heligoland, in the River Elbe and in the Great and Little Belts. Low cloud over the German and Danish Coasts forced the minelayers to fly low in order to establish their positions before laying their mines and much German light flak activity was seen. 22 aircraft - 7 Lancasters, 7 Stirlings, 6 Wellingtons, 2 Halifaxes - were lost. This was the heaviest loss of aircraft while minelaying in the war, but the number of mines laid was the highest in one night.

Among those lost was Patrick’s aircraft which was on its return flight when ,at 1:29 a.m., a German flak battery at Oddesund Bridge in north-western Denmark opened fire and hit the aircraft. The pilot, Kenneth Rees, attempted to land the aircraft in a shallow inlet off the North Sea known as Nissum Bredning, a hundred yards from Remmerstrand. The aircraft broke into three parts and caught fire. All on board died as a result. of the incident.

Kenneth Rees' body was recovered from the aircraft by the Germans. George Tyler was found washed ashore later that morning. Thomas Ellingsham and Leonard Foulds were recovered in the early afternoon close to one another. Alexander Cochrane was found later in the day by a fisherman on fish traps having died from exposure (his body was not positively identified until 1998).

The five were buried at Lemvig Cemetery in Lemvig, Denmark on 5th May 1943. Patrick's body was washed ashore at Remmerstrand on 16th May 1943. Two weeks later Stanley Cowham was found near Humlum (he too was not positively identified until 1998). Both were buried at Lemvig Cemetery on 4th June 1943. Patrick lies in grave 704.
